IMIPROVVEMENT IN SPRING BED-BoTToms.

Specification formingpart of Letters Patentllo.l 1189.104, dated April 1877; application tiledv k A December 21, 18,76. v 4

To all whom t may concern l Be it known that, I, THEODQRE R..JONEs, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Spring Bed Bottoms;

and I do hereby declare that the following isA a full, clear, and exact description thereof, which will enable others skilled in the art to which it 'appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a top plan, Fig. 2 is a side elevation, and Fig. 3 shows, in detail, one of the hooks E detached.

,Similar letters of reference 'indicate corresponding parts in all the figures.

This invention relates to spring bed-bottoms; and it consists, rst, in the improved construction of the frame, and, secondly, in the construction of the hooks, by which the springs nearestgto the frame are connected thereto, all as hereinafter more fully shown and specified.

In the drawing, A is the lower part of the frame. This consists of two longitudinal bars, A1 A1, having transverse slats a a. In order to insure strength a third bar, A2, may be secured under the middle of slats a, as shown. A3 is a cross-brace connecting bars A1 A1. The employment of this cross-brace enables the frame to be made of very light material, preventing it from bending and warping. At the ends and middle of bars A1 are uprights B, upon'which rests the upper frame C, it being secured by bolts passing through uprights B. Frame C is somewhat longer than frame A,'so as to accommodate the springs placed upon the end slats of the latter. The inner sides of the bars forming frame O are beveledyas shown at c c, for the purposes hereinafter described. D D are the springs. In placing these upon the bottom I prefer to arrange them diagonally, as shown, the object of this being to provide an easier bed by causing the body of the occupant to restupon a larger number of springs than could be the case if they were placed at right angles. The outer springs, or those nearest to frame C, are connected therewith in the following manner: E E- are v links vor, hooks consisting of pieces or strips of wire having at each end an eye or hook. 'One of the ends e is hooked over the upper coil of the spring, and the other end is bent, as shown at e', and secured by means of a self-clinching staplehook to the upper side of frame C. The inner sides of this frame being beveled, the links E are permitted to work perfectly free when the springs are depressed, this being also partly due to the fact of their being bent atv e. Apart from this, this method of connecting the springs to the frame is very efficient in keeping the former in position, and it is preferable to those bed-bottoms in which the connecting-links are secured to the under side of the upper frame, inasmuch as it leaves no space for the mattress and bed-clothing to settle downin, the result of which usually is that the springs and links become prematurely worn out and unfit for use.

The tops of every four springs are connected by means of wire hooks F in the following manner: Over the upper coil of each of the four springs, one end of each hook (or link) is secured; the other ends ofthe links F are then connected by means of a fifth link, G', twov of the links F being hooked onto each end of the link G. By connecting all the springs of the bed in this manner a very large number of joints is produced, thus permitting the bed to easily adapt itself to the occupant, and yet dividing the pressure evenly over the entire surface of the bed.

The operation and advantages of my improved spring bed-bottom will be readily understood from the foregoing description.

The double frame A C serves to protect the springs and keep them in place. The couplings by which the springs are connected with each other and with frame C equalize the wear upon the springs, and connect them firmly enough to keep them in place, and prevent them from slipping over, and yet, as will be found by experiment, each spring may be depressed almost independently of the rest, an object which, owing to the fact that a softer and easier bed is produced, is of great importance in the manufacture of spring-beds, and, in fact, in all kinds of furniture where springs nrelused, `and which is accomplished .ailinosttoperfection by my improved method ofconpling or connecting the springs.

My improved construction of the couplingy links E, in combination with the slanting or inclined sidesoi' frame C, permit all ,of the springs, even thos'eclosest to thefframeC, to be depressed to their full capacity, thus giviong additional elasticity and comfort to the ed. v A,

Having thus described my invention, I

claim and desire to secure by LettersPatent of the United States'- 1. The double frame for spring-beds, lherein Y as and for the purpose herein shown and speciiied.' f
